My 09 ES350 2GR-FE V6 NA has 62k mi and it is on its 1sr Valvoline Restore and Protect. The last 20k or 8yrs it has been on a Pennzoil Ultra Platinum, Mobil 1 and Quaker State. Previous 40k, an unknown oil used. Fall time, it is going to be interesting to what carbon I find in the filter cartridge.
